Thanks for reporting this and sorry for the trouble. You're running Kiro version 0.12.x, and we've shipped several major releases since then (1.0.0 through 1.0.138) that include many improvements and fixes:

• Rebuilt connectivity and session management
• New permissions system
• Compaction loop fixes (Context limit exceeded errors)
• MCP reliability and OAuth improvements
• Performance optimizations

Could you please retest on the latest version (1.0.138) from https://kiro.dev/downloads and let us know if this is still an issue? If we don't hear back within 7 days, we'll assume it's resolved and close this out.
